I was planning on using the 3ft cables from iofast, but they are now discontinued (from everywhere - i've called around). Because of this, I ended up using your regular SPT2 extension cords. I am glad i did that, because i now have 6 foot cords coming out of the LE - this way i won't have to use so many extension cords when I set everything up.
The long cords make the LE a little more bulky and heavy, but that's not a big deal to me. Just makes storage a little more difficult.
